In general, household fans run on 120 volts AC (volts alternating current), which is also called line power. The wire that connects the motor to the fan will be either 14 or 22 gauge wire. 14 gauge wire is usually used for small motors while 22 gauge is recommended for larger ones.
The type of plug that you use with your fan is called a continental plug. This plug has two holes: one for the ground pin and one for the hot pin. Before you start working on any wiring project, make sure that you know what kind of plug you need by checking the label on the back of the fuse box or circuit breaker. Then look on the fan itself for manufacturer's instructions on how to connect it up. If there are no instructions, then we will show you how in a minute.
Now let's take a look at how to connect up a 12-volt fan. First, find the black wire from the battery and connect it to the red wire from the fan. Then connect the white wire from the fan to the green wire from the battery.
The cooling fan relay is usually found in the underhood fuse and relay center or on the electric fan assembly behind the radiator. This electrical switch controls the power to the fan when it is not being driven by the engine's controller (ECU). The switch may be either a contactor or a triac. A contactor can handle up to 100 amps of continuous current while a triac can only handle about 30 amps. Contactors are generally used for fans that run all the time like the one on your car's air conditioner while triacs are usually used for fans that turn on and off with the engine's controller, such as the one on your car's heater core.
Contactors are normally closed (they close when you put electricity into them) so they must be opened by removing the fuse that protects them from overload damage. Most fuses that protect fans are designed to open when the load they are protecting reaches 75% of its normal value which should be enough to keep most fans running but would shut off a very heavy-duty motor if it reached its maximum capacity. Triacs are normally open (they open when you remove electricity from them) so they do not need to be removed to check their status. You could also simply touch two wires together to test this circuit without removing the fuse.
The most popular method is to connect a ceiling fan with four wires. An additional color wire, however, may be included. Each wire color signifies the following: Household: The hot wire, which leads to the switch, is the black wire. It should be 12-gauge or larger for safety reasons. If it's not, then it should be treated as if it were live current even if it's not being used as a circuit conductor. Commercial: The white wire is the neutral wire. Fan: The green wire is the ground wire.
In other words, a ceiling fan should have two black wires, one white wire, and one green wire entering it from above. From there, they go into your electrical box, where they meet with another set of two black wires and one white wire. You'll need to join these three sets of wires together before putting them into your wall space. This is called "splicing" the wires together.
Connect the negative input clamp (black) to the automotive battery's negative battery post (-). Turn off the fan power switch. Connect the fan to the power inverter. The positive terminal of the inverter should be connected to a good, strong source of voltage such as a car battery. The red cable goes to the positive terminal of the fan.
The power inverter can be any type of unit that converts 120-volt AC power into 6 volts DC power for use by 12-volt devices such as fans. These units are available at home improvement stores and online. In addition to being easy to install, they're very effective in reducing energy consumption during periods of low activity. They can also extend the life of certain appliances not designed to operate on high voltages.
Installing a power inverter is easy if you have some basic tools. You will need a multimeter to make sure there are no electrical problems with your vehicle before you begin. An auto electrician can help you diagnose problems with your wiring or appliance connections if you have any questions about how it works. For example, he or she might show you which wires go where on your dashboard/bodywork.
Once you know what needs fixing, an auto electrician can help repair or replace any defective parts of your vehicle's electrical system.
To install a fan speed control switch on an existing fan, you must first identify the wires that feed electricity to the fan. This is due to the fact that you will have to cut the cables and put the switch in line with the fan. Locating this wire might be difficult at times, but you can usually follow the cable's basic course. The black wire is usually the one to cut.
After cutting the black wire, remove its covering tape or insulation from around the copper core. Next, strip about an inch of white plastic coating off the other end of the copper core. Now take the new switch and connect it directly into the black wire using the white plastic coating as needed for electrical contact. You should now have two hot wires coming out of the wall box that will operate the fan when you turn this knob here! If your fan has more than one wire feeding power into it, such as three or four, you will need to select which ones to use by turning which screws here. Make sure that you do not mix up the wiring of one fan with that of another! It is important to note that if you are switching several fans from one circuit to another, you will need multiple speed control switches. One switch per fan will not work because each switch only controls one fan.
What if your fan doesn't have a speed control switch? That's okay too! Just make sure that you don't have any circuits feeding power into the fan without a speed control switch.
